Table 2. Remote Annex Port Mode/Service Restrictions
Note that if Service-Type (6) = Callback-Framed[4], the user is granted
access but will not be called back.
Dialback Services
For the Callback service types (Service-Type (6) = Callback-Login [3],
Callback-NAS-Prompt [9]), the Remote Annex will dial back the user
with the phone number specified in the Callback-Number (19) attribute.
If this attribute is not returned by the RADIUS server, the user is prompted
for the number. Specifying the callback number in the RADIUS server
is more secure than having the user provide it at the prompt.
The Remote Annex dials back the user on the same channel on which he
or she dialed in. Dialback calls are reauthenticated (and reauthorized) as
if they were new calls.
